The most direct route by car is about 12.5 miles, using either the interstate, or a parallel 55 MPH state highway (both get TONS of traffic). No way, no how.

Of the other 2 available routes, the shortest (14.5 miles), mostly to the east of the interstate, includes some rather large hills on a couple of roads with moderate traffic including big trucks. I went this way when starting out, but then discovered traffic to be a beast when school started back, so I rarely take that route anymore.

My route of choice is a mile longer than the first route at 15.5 miles, and is mostly west of the interstate. Traffic is much, much lighter, and there is less climbing in both directions. My best time has been less than 65 minutes. Worst time more like 85 minutes.
